I hope he quoted Matthew Ch4, v4
Very good. That was a very popular game with Naval Officers of my Dad's vintage; trawling through the good book in search of suitable biblical references for signals.
He put it to good use many years later when our border collie bit the vicar on the backside. It was the Vicar's fault really, as he was on a bicycle, and Maggie hated bicycles.
My Pa told the Reverend that he'd find the relevant passage in the good book at Matthew 5:39. To my Dad's great satisfaction, , the Vicar had to pop home to check the reference.
